If you are going to buy one bolt for your Impulse make sure it a New Designz, this baby rocks! Field testing has shown an increase in velocity of 12-30 fps over the stock bolt. This increase will significantly lower the pressure of your Impulse. Plus, the bolt is made out of Delrin which will not wear your Impulse like the stock bolt will. The last notable difference with the New Designz Impulse Bolt is how light it is. Weighing in at 29.5gr, versus the stock bolt at 54.6gr, allows the Impulse to cycle faster with less stress on the internal parts. Get yours today and get the New Designz difference! |
